Article 4
— Separate sale of regulated retail data roaming services

Roaming customers shall have the right to switch roaming provider at any time. Where a roaming customer chooses to switch roaming provider, the switch shall be carried out without undue delay, and in any case within the shortest possible period of time depending on the technical solution chosen for the implementation of the separate sale of regulated retail roaming services, but under no circumstances exceeding three working days from the conclusion of the agreement with the new roaming provider.

The switch to an alternative roaming provider or between roaming providers shall be free of charge for customers and shall be possible under any tariff plan. It shall not entail any associated subscription or additional fixed or recurring charges, pertaining to elements of the subscription other than roaming, as compared to the conditions prevailing before the switch.
